TRAFFIC GUIDE.

Original No. 1,479,227, dated January 1., 1924, Serial No. 639,982,filed May 18, 1923. Application for reissue filed January 30, 1925.Serial No. 5,906.

' To all whom it may concern:

, Beit known that I, THOMAS G. URETNEY, a. citizen=of the United'States,and a resident of Madison, in the county of Dane 6 and State ofWisconsin, have invented an Improvement in Traffic Guides, of which thefollowing description, in connection with the accom anying drawings, isa specification, like c aracters on the drawings representln like parts.

My mvention relates to a practical means for directing trafiic at streetjunctions and intersections; and the objects of my invention are, first,to provide a durable metal guide to be placed in, and secured to thecenter of a street; second, to have words of instruction cast on theguide in letters (that will retain their distinctness under the wear oftraflic); third, to so locate the guides adjacent to the streetintersections and danger, oints that obedience to the instructions tereon will effect proper regu-.

lation of the movement of tratfic and prevent accidents.

In the accompanying drawings, wherein 'is selected for illustrativepurposes one embodiment of my' invention;

, Fig. 1, is a diagram of a street intersection with four guldes inposition;

Fig. 2, is a plan and Fig. 3 is a front elevation of the guide; and

Fig; 4, is a vertical section on line A- --B in Fig. 2, showing also aortion of concrete street to whichthe guide is anchored.

In the embodiment of my invention illustrated in the drawings, the baseor casing 1 is dome shaped and preferably is of metal formed as a hollowspherical segment and provided with a plurality .of depending anchors orcalks 2 spaced around the bottom near its outer edge or periphcry. Theanchors or calks 2 may be of any suitable shape adapted to resistmovement. of the device. As shown, said calks depend at right angles tothe base on their right hand edges, but diverge from the point on theback andinside surfaces, giving support to the point. The base or casing1 is 1-. formed with an opening 3 through the center thereof. and withpockets 4 in the upper face near the periphery of the casmg.

Preferably these pockets are in alignment -'with and directly over theanchors or calks 2, and may be shaped to correspond with the shape ofthe points of the calks 2, to facilitate stacking one upon anotherduring manufacture and acking for transportation. A. bolt 5 wlth a head6 and hook 7 is provided for securing the base or cas ing tothe surfaceof a street at the desired location.

On the upper surface of the base or casing 1, and preferably upondiametrically opposite sides thereof, are cast suitable traflicinstructions or indicia, such as Keep to Right. The letters constitutingsuch indicia are preferably cast or otherwise formed in the metal, andare advantages ously raised a sufiicient distance to protect the-paintupon the body of the casing from wear and damage when struck by avehicle wheel.

My guides may be readily and permanently installed in connection with awide variety of pavements. A. hole is first drilled in the street at thedesired location, large enough to receive the hook end of the bolt. Asmall hole is then drilled for each of the calks 2, and the casing isset in place with the indicia transversely of the street,

that is, facing the direction of traflic thereon. A thin mixture ofcement and water is next poured through the hole 3 into the hollowcasing, and the bolt 5 is inserted through the hole until the head 6rests upon the casing 1. When the cement hardens the guide will besecurely located.

In the case of Keep to the right guides, each device is locatedpreferably in the middle of the street slightly back from the line ofthe curbing of the intersecting street, as shown in Fig. 1. In actualpractice, in many instances I find it advantageous to place the guidesadjacent to the line of the crosswalks of the intersecting streets.

In the diagram Fig. 1, it will be seen that a car 0 makingaright handturn from street D will enter into the traflic on the right side ofstreet E at C and going straight through will reach C If making a lefthand turn the car will be in line with the trafiic on street E at Cthereby eliminating confusion at such laces.

- My guide will a so be useful if placed at intervals in the center ofaved country roads to keep traflic separate at a safe dlstance. Otherlocations and uses for uides embodying my invention will be readi yoccurvto those concerned with the regulation of traflic. v

Myinvention is not restricted to the details of construction shown anddescribed.

What I claim is- 1. A trafiic guide comprising a hollow convexed segmentof metal with a plurality of dependingcalks around the bottom thereof,said calks being at right angles to the base on their right hand edgeand diverging to their junction with the base, pockets for each of thecalks, and with a hole through the top of the guide for holding anattaching bolt or through which cement may be poured, the top of theguide afit'ordin a prominent field for displaying traific 1n 1cm.

2. A traflic guide comprising a hollow convexed segment of metal formedwith a lurality of depending calks around the bottom, thereof and withpockets for said calks in its top, and a central opening through 'the'top through which an attach-- ing bolt may be secured and through which.cement maybe poured, the top of the ide being formed to present aprominent eld for traflic indicia. p

3. A 'traflic guide comprising a hollow convexed segment of metalaffording a field for trafiic indicia on its top,'said segment beingformed with a plurality of depending calks around the bottom thereof andwith a; plurality of pockets each above one of the calks, and said guidealso having a central opening adapted to receive an attaching bolt forsecuring it to adjacent guides for shipment or to the pavement.

4. In a traflic guide, a hollow metalcasing presenting in its entirety arelatively low lying structure, and a filling of cementitious materialfor supporting-said casing thereby to constitute a solid, metal armored,member affording a suitable field for integrally formed traflicregulating indicia.

5. In a traffic guide, a hollow metal casing presenting in its entiretya relatively low lyingstructure, peripheral anchoring means connected tosaid casing and embed ded in the avement, and a binding element ofcementitlous material adapted to fill and Support said casing, therebyto present a so 1 d member'adapted to withstand trafiic,

the top of said member afi'ording a pro1ninent field for displayingtraflic indicia.

6. In a traflic guide, a hollow metal shell havin sloping sides forforming a promi nent neld for traffic indicia and capable of beingnested within another shell of similar .lying structure and having animper orate upper surface except for a central opening to receive acent-ralanchorin means, and

central and peripheral anchorlng means for securelyfixin said casing toa avement.

9. In a tra 0' guide a hollow ome shaped metal casing presenting in itsentirety a relatively low lying structure, central and peripheralanchoring means connected to said casing and embedded in a pavement, anda binding element of cementitious material adapted to fill said casingand securely anchor said central anchoring means in said pavement.

10. In a traflic guide, a metallic member, depending anchoring elementson the bottom of said member, the outer face of said memher being formedwith seats for the depending anc oring elements of another guide, when aplurality of guides are nested together.

11.,A trafiic guide comprising a hollow metal casing presenting arelatively low lying structure, central and peripheral anchoringelements for fixedly securing said casing to a pavement, and a fillingof cementi'tious material for said casing and surroundin said centralanchoring element, the top of therasing sloping-in opposite directionsand forming a prominent field for displaying trafiie indicia.

12. A traflic guide comprising a low cementitious body suitably fixed tothe surface of-a street or pavement, a, metal armor for saidcementitious body, means for securely fixing said armor to the surfaceof the street or pavement, said armor being imperforate except for anopening to receive a securing means and being suitable for receiving anddisplaying traflic indicatin indicia and withstanding the wear of trac.

13. In a trafiic guide, a metal casing, in combination with peripheralcalks depending from the bottom of said casing, and pockets formed inthe top of the casing in alignment with and directly above said calks.

14. In a trailic guide, a metal casing, in combination with peripheralcalks depending from the bottom of said casing'and tapering towards alower point, and pockets formed in the top of casing and shapedcorrespondingly to the point of said calks in alignment with anddirectly above said calks.

15. In a traflic guide, a metal casin in 5 combination with a pluralityof space anchoring elements depending from the bot tom of said casing,and pockets formed in the upper faceof said casing and spaced apartcorrespondingly to the spacing of said calks.

In testimony whereof I have signed my name to this specification this26th day. of January, 1925.
